pest would hide. Since kakawate is a legume, says Rabena, its leaves are rich in nitrogen, an important soil nutrient. Hence, the discarded leaves can be applied to the field as an organic fertilizer. He also recommends fanners to put several leafy branches of kakawate tree in between rice plants two days after planting to prevent pests from attacking the crop. To prove this research finding, Rabena and Flora Cely Rodilias did a demonstration in Naglaoa-an, Sto. Domingo, Ilocus Sur as well as in Vigan

weeks under natural conditions and 2-3 days under wet conditions germination of seeds must occur in short period of time. Cottonwoods can also reproduce asexually through crown breakage and tree fall during wind storms and flooding events. The broken branches after being buried in sediment sprout and develop strong shoots. Species, climatic condition and drainage basin of the area determines whether the seedlings are established more from sexual reproduction or asexual propagules may outdo seedlings in

components of the scientific method because they result in valid and reliable scientific statements. All the different fields of the sciences form scientific statements which deepen our understanding of the universe. For example, biology which is one of the major branches of science focuses on the science of life and living organisms. Chemistry is the branch of science concerned with the composition of substances, their properties, and their reactions. Physics is yet another branch of science which

Introduction The Daphnia magna, more commonly known as the water flea, is a tiny freshwater crustacean. Its clear exoskeleton and jointed appendages point to its classification as an arthropod. This is further evidenced by the location of its heart—the dorsal region. The Daphnia magna’s importance in the aquatic food chain can be attributed to its essential place in the diet of young and adult fish (Elbert, 2005). The Daphnia magna belongs to Class Branchiopoda, which are free-floating crustaceans

system. Traditionally, neuroscience has been seen as a branch of biology. However, it is currently an interdisciplinary science that collaborates with other fields such as chemistry, computer science, engineering, linguistics, mathematics, medicine and allied disciplines, philosophy, physics, and psychology. The term neurobiology is usually used interchangeably with the term neuroscience, although the former refers specifically to the biology of the nervous system, whereas the latter refers to the entire

Plant propagation is the process of creating new plants from a variety of sources: seeds, cuttings, bulbs and other plant parts. Plant propagation can also refer to the artificial or natural dispersal of plants. Sexual Reproduction – pollination (plants or trees that have flowers) Asexual Reproduction *Natural *Artificial Natural Methods of Asexual Reproduction Natural methods of asexual reproduction include strategies that plants have developed to self-propagate. Many plants, such as

Bhagyesh Parna BUS 151 09/16/2014 The World Is Flat Growing up I learned about the process of adhesion in my biology class that occurs between water molecules. Adhesion is a process in which dissimilar molecules attach themselves to each other due to various inter-molecular forces. An example of this could be the water droplets attached on a leaf surface. In his speech Thomas Friedman explains a theory very much similar to this called ‘globalisation’. In today’s world there is a large presence

What is dissolved oxygen? Dissolved oxygen alludes to the level of free oxygen not bonded to any existing molecule in the water or other liquid substances. It is an important parameter in assessing water quality because of its influence on the organisms living within a body of water. In limnology (lakes studies), dissolved oxygen is a crucial factor second only to water itself. A dissolved oxygen level that is too high or too low can harm aquatic life and affect water quality. Non-compound oxygen

Lichens occur from sea level[->11] to high alpine[->12] elevations, in a very wide range of environmental conditions, and can grow on almost any surface.[7] Lichens are abundant growing on bark, leaves, mosses, on other lichens,[6] and hanging from branches "living on thin air" (epiphytes[->13]) in rain forests[->14] and in temperate woodland[->15]. They grow on bare rock, walls, gravestones, roofs, exposed soil surfaces, and in the soil as part of a biological soil crust[->16]. They can survive in
